High Resolution Issue

[CClinic]

I have an Acer Laptop with 4K (3840 x 2160) resolution, all dialog boxes and fonts are very small. I tried to change the resolution to (1366 x 768) but the everything became bigger and a part of the screen was cut off, the only resolution that is working is (3840 x 2160). I tried to increase the font size to 500% and i increased the size of menu font but it did not work. I updated drivers via windows update, i also tried downloading the original drivers from nvidia website and acer website, but nothing worked. When i run cmd it is very small with small unreadable font, even if i maximize it. The dialog boxes in AutoCAD are also small, some words can't be read. Please Help!

Have you tried checking the settings in "Control Panel" and then "Ease of Access"?
